Screen stays on while you tune - Fixed an issue where the screen could dim or lock while tuning. It now stays awake until you're done. Also in this release - Fixed a problem that could stop lessons from loading correctly. Thanks for tuning with us, your feedback shapes every release, so keep it coming!

Screen shoot off

I had to tune both
6 and 12 strings guitars and by the time I finished, I already open again and again multiple times the screen because the timer of the active screen is really short. This is so frustrating. Why is this happening. I want the application to remain with the screen “on” until I finished the tuning. Please someone, educate me!

Couldn’t tune my guitar without it

Accurate and Reliable

Some tuners are better than others. This was the best one I could find.

Very reliable

Thanks. It’s always handy on my phone.

Update…

Update came…
„Activate microphone for…“
Can‘t do it since there is nothing in the settings. Neither iOS nor Tuner.
And why do I have to reactivate my premium account after every update?
Password, I don‘t remember…
No information if the given email address is registered or not (multiple accounts, therefore one sometimes forgets things one uses only once a year or less)…
WHEN in works, it’s a pretty fine tuning app….
